Option 2. Limit Refrigerant Leakage (1 point)

Design, construct, and operate the project’s refrigerant-using equipment to minimize refrigerant leakage. For initial build-out of projects with less than 50% of the capacity of refrigerant-using equipment installed in the project scope of work, compliance must be documented for base building systems as well as any systems installed in the project scope of work.

Design Refrigerant-using equipment shall be self-contained, with no field-installed piping:

  • For equipment with refrigerants > 700 GWP AND

  • For at least 80% of the total GWP of refrigerants used in the project

Specify an “automatic leak detection” system in fully enclosed spaces with equipment that has an overall refrigerant charge exceeding 100 tons of equivalent CO2 emissions (tCO2e).

Installation Field-installed refrigerant piping shall use brazed or press-type fittings.

Operation Have in place a refrigerant maintenance plan and designate a responsible oversight party. The plan shall include standards for recordkeeping and protocols for:

  • Updating the refrigerant inventory.

  • Tracking and recording refrigerant charge and leakage rates for all refrigerant-using equipment.

  • Ensuring that installation, maintenance, and removal of refrigeration-containing equipment is performed by appropriately certified refrigeration personnel, including in tenant spaces.

  • Auditing annually and calibrating automatic leak detection systems.
